If you look at the table here x86 and x64 are the only supported host
architectures. But that's OK, the x64 binaries will run on arm64 (W11
ARM64 has x64 emulation builtin). If that didn't work Dave and I would
not have got as far as we have. But you want the x64_arm64 argument to
vcvarsall so you will get ARM64 output.
